A great new product is off the production line at Sewell Direct. The SilverbackSL is a self-crimping connection, for all inputs that are spring-loaded, or simply accept a wire only connection. The SilverbackSL marries the beautiful and sturdy design of the Silverback Banana plug, with the need for wire connection. We"ve developed a special non-conductive coating for our aluminum casing on the Silverback, which will inhibit the plugs from electrical conduction, ensuring the user a perfect connection, with no worries of shorting your speakers.
